RESOURCES FOR FINDING YOUR SATA HARD DRIVE JUMPER CONFIGURATION

The new SATA drives don't require any jumper setting changes on your Macintosh (MOST OF THE TIME). If you are on an iMac G5 and install a new SATA drive you will need to slow down the drive by adding a jumper. If you are using a drive from an iMac G5 and putting it in a later machine you need to remove the jumper. Your drive should be recognized by the disk utility and allow you to format it. If it doesn't suspect jumper settings. The regular tower Power Mac G5 systems had the faster bus. PC's may require it depending on your motherboard. Why you should check a SATA drive's jumper settings - YouTube.

Some of the early iMacs and MacBooks, MacBook Pro's may have trouble talking to the new 6GB drives that are now available. If your unit has the 1.5GB drive bus you may want to install the jumper. Another article I found useful was from Accelerate Your Mac. It has a diagram for setting the Seagate drives down.

RESOURCES FOR FINDING YOUR IDE HARD DRIVE JUMPER CONFIGURATION

They call IDE drives ATA and more recently PATA. It is for our intents and purpose all the same. Do scrutinize the drive itself. Many times the settings chart is right on the drive. Knowing the settings is important for to easily install hard drive they are required.

How to configure your drive jumper settings for:

Hitachi/IBM - Hitachi bought IBM's Hard Drive Division. This link is to their drive setup site. The jumper table is on the end of your hard drive.
Seagate/Maxtor/Quantum - the Seagate site is crap now. Use my Seagate/Maxtor/Quantum Drive Table.
Western Digital - http://support.wdc.com/ - look on the circuitboard near the jumper position or click here for the universal chart..
Samsung - had to do their own thing so pay attention: drive configurations Samsung Chart. The chart on the drive makes no sense. I don't think much of these drives by the way. They have a high failure rate. They went out of their way to show you how to limit your drive to 32GB for what reason I cannot imagine.

RESOURCES FOR FINDING YOUR SCSI HARD DRIVE JUMPER CONFIGURATION

SCSI JUMPERS - most SCSI drives use the small size jumpers. This is a link to Seagate/Maxtor/Quantum site. From there you can find the jumper settings for your drive Click here for drive hard jumper maxtor setting Maxtor/Quantum - http://www.maxtor.com/home-en-us.html

SCSI drives use jumpers for several functions. The main reason most people change the jumpers on a SCSI drive is to give it a different SCSI ID. There are usually 3 locations and on the Quantum for example they are labeled A2, A1, and A0. Default is generally no jumpers which makes the drive 0. By adding jumpers to different positions you can number the drives anywhere from 0 to 7. The main thing is to make sure that the number you make the drive is different than any other device on the chain. For example a typical installation would be a base drive with the number of 0, a CD drive with the number of 3, a zip drive with a number of 4, and a scanner with a number of 7. If you were to add an additional drive to this chain it would have to be numbered 2,5, or 6.

The other reason to jumper a drive is for termination. It seems systems like to know where the beginning and ending of the chain is. To accomplish this the first device on the chain generally should be terminated as well as the last device. See the notes on your system for specifics. I like to have my scanner as the last device in the chain and I always terminate it. Want to know more about termination? Try http://www.scsita.org and look up termination.

Startech has a SCSI School which is a great place to learn about all the flavors of SCSI http://www.startech.com/scsischool/

IDE/ATA/PATA DRIVE JUMPERS - all IDE/ATA/PATA drives use the large size jumpers.

IDE/ATA drives generally have 3 or 4 jumper positions. If you have two drives on a bus you must configure the drives in a master/slave configuration which may require you add a jumper to one drive or the other. See your drive instructions or try the appropriate site listed in the links.

SPECIAL NOTE: ON Power Macintosh G4 systems produced after 2002 which includes late model QuickSilver G4's, Mirror Drive Door, iMac G4's, Mac Mini"s, iBooks, Powerbooks having Boot ROM Versions 4.33 or later you should use CABLE SELECT on all drives including opticals. This includes all G5 model opticals as well. The G4 units do not have the 132GB hard drive limitation and can use the larger IDE drives. Do remember though that if you plan to boot info OS9 on units that are capable, the maximum partition size is 190 GB.

Why DriveJumper.com?

In a word you can't find these anywhere anymore and if you do they want you to buy $50 minimum or pay through the nose for shipping.

I started this service for those of you in this position. Not only do I have the links to get the information for setting up your drives all in one place I also added the best sites with overclocking information.

I usually drop them when working and my wife vacuums them up when I am not looking.

I also added some drives to these systems and on some I had to change the SCSI ID's and termination and on the IDE drives I had to set up Master Slave configuration. Again I needed jumpers only this time a different size. I had a heck of a time finding the information on setting up the drives.

When we configure G3 Systems we sometimes overclock (speed up or optimize) the processor on these unit easily. Or so I thought. Some of the configurations require 6 jumpers. I couldn't find the small size jumpers anywhere. Radio Shack didn't have them in stock. I finally found a source that would sell me in 100 lots but I had to make a minimum order and pay shipping just so I could get 5 extra jumpers. The drive hard jumper setting was sometimes hard to find.

Now you can get the jumpers you need without having to pay an arm and a leg for shipping and get help finding out how you are supposed to configure your equipment in one easy to use place.

New SHORTY Size Added!

We now sell three sizes of jumpers. After buying some new SCSI drives I found I needed a low profile jumper for them. The small and the large (gold plated small, tin plated large) come in a package of 6 for a fair price and no tax except in Oklahoma. They are $1.99 your choice of sizes. The new SHORTY size we sell 4 in a package for $1.99. We include shipping in the price (we mail your order first class). If you aren't sure what size you need order the combo pack which includes 6 each small and larger for $2.99. The SHORTY jumpers we only sell separately and you will know if you need these since they are so small and SHORT.

Bob, why don't you sell or recommend the new SSD type drives

Well if you haven't noticed they are still too damned expensive for my pocket. If you do decide to buy one I would recommend OWC since they have units designed for the Mac and stand behind the product. We can special order one and install it on any system we build with your request.

We plan on offering a 120GB SSD with adapter that will work in your BWG3 and G4 Macs very soon. See our IDE drive section..

That being said we have started installing Seagates NEW Hybrid Drives on a few of our frequent customers custom system builds.

Seagates NEW Hybrid Drives offer the best of both worlds

If you haven't see these they offer the best of both worlds. A good size SSD is built into a conventional size hard drive giving you SSD performance and regular drive capacities.

Seagate has 1 Terabyte, 2 Terabyte and 4 Terabyte capacities in a standard 3.5" full size capacity for both G5's and Mac Pro Towers or your older G4;s if you have a SATA card installed.

Seagate also offers 500 GB and 1 TB capacities in the 2.5" Laptop sizes. The larger one will not fit in some units since it is the taller size.

While we aren't stocking these yet Cheryn will be happy to quote you a price on one delivered or installed on your system. Do remember we can do our installs (extra fee) that will get you up and running immediately and we have the G5 mounting screws in stock.

COMMERCIAL MAC HARD DRIVE RECOVERY

  • If you have data that absolutely must be recovered, for Mac HD recovery we suggest a place called DriveSavers. Tell them we sent you and get a 10% discount by giving them the number DS20072. They have a no data, no charge, policy on single drives. I would get an estimate. Call them toll free at 1-800-440-1904. To request an estimate by e-mail, log on to our website at http://www.drivesavers.com/estimate

    Remember here at Headgap we do what is called level 1 recovery. If the drive isn't making bad noises and is just not mounting we can likely get your data back and possibly simply restore the drive.

    HARD DRIVE LIMITATIONS:

    The G3 and G4 prior to the QuickSilver 2002 model has a limition on drive size. 132 GB is the maximum drive size for units made prior. Practically speaking an 80GB or 120GB is about all you can find.

    NEVER INSTALL A 160 GB or Larger Drive internally and format it to a smaller size. This will bite you on the butt, guaranteed. I don't care if you did get it for a nickel after rebate.-

    WARNING: If you are planning on buying a large-capacity 3.5" internal hard drives above 128 GB, you need to be aware of this issue, in case you are not already:

    The ATA controllers in Macs up through the PowerMac G4 Quicksilver 2001 models cannot properly format a drive larger than 132 GB, and entire drive will not be recognized. For example, when upgrading a G4 Quicksilver 2001 with a 160 GB hard drive, only 128 GB of storage will be recognized if using the native ATA controller. We stock an ATA card that solves this issue but better yet install a SATA card.

    All ATA133 controllers allow large capacity hard drives to be formatted for their full capacity, even in systems where this was not natively possible (Quicksilver 2001 and earlier). We or course keep the 133 Cards in stock.

    If you are looking for the ultimate and have a few more bucks to spend search out the new Serial ATA drives and the new Tempo ATA150. These are probably a waste of money for anything but the fastest hardware though. They do offer convenience.

    External Firewire drives do not always have this limitation but you should check with the manufacturer before buying a housing with plans to put in a larger drive. Some el cheapo housings may not support large drives.
